"The No. 1 priority is always the safety of passengers," said Palm Beach County Mayor Steve Abrams, who supports these new regulations.

Cab companies would be required to have stricter standards on the age of their fleet.

They would also be required to take credit and debit cards, which is good news for everyday travelers, but might cost a cab company a lot of capital up front.

Cab drivers also would be required to clean up their cars and dress more professionally.

"You really don't want get into the business of telling someone what they can wear," Abrams said. "So maybe some minimal standards like collared shirts so you're not showing up in a T-shirt or cutoffs."

Some cab drivers said they already dress to impress and don't want the government telling them what to wear.
